Question

DentroTest · Accepted Answer

Spanish traffic regulations establish different documentary requirements based on the mass of the trailer: Light Trailers (MAM ≤ 750 kg): Do not need their own registration certificate. They circulate under the insurance and documentation of the towing vehicle, although they must have their own ITV (MOT) card. Non-Light Trailers (MAM 750 kg): Are considered administratively independent vehicles. Therefore, it is mandatory for them to have their own registration certificate, their own red background license plate, and independent insurance.
